Eurgh yes I hate the immediate demotion of Daisy. I don't even understand that bit when Jo tells Daisy how relieved she is that Laurie will be there: is it supposed to acknowledge that Daisy's knowledge is now out of date or has been erased from her brain? Surely EBD hasn't actually forgotten that Daisy was the paediatrician until five minutes earlier?
Conversely, I like that for the most part the mistresses in the first chapter of Exile actually give Jem something of a hard time and ask awkward questions, rather than meekly accepting that he is right and they must move up to the Sonnalpe under the protection of seven British doctors (against the third reich, seven British doctors!).
I am frustrated by how many Dramatic Rescues ultimately necessitate the involvement of the menfolk. I don't exactly want a complete absence of men, and for example Jack and Gottfried in Exile are nothing short of brilliantly helpful and that seems fine, it's just the inevitable appearance of Random Man As Saviour Of Last Resort that grates.
I can't quite believe that EBD knowingly included lesbian relationships in children's books, but I also really don't believe she was entirely naïve in this regard. I have wondered before whether Nell Wilson and Con Stewart, in particular, were an accidental portrayal of a pair she knew IRL and hadn't twigged the extent of their relationship - I still think this has some credibility, more so than most alternatives IMO. But I also wonder if some of it comes down to her semi-unconscious style of writing - I think sometimes her characters don't behave exactly as she'd intended: I think perhaps there is accidental lesbianism because she did know something about it and wasn't paying enough attention to keep it out.
I also think it's interesting that she mostly avoids the whole 'crush' thing, apart from Tom's adoration of Daisy and Rosalie's of Tom - I think it's interesting that she chose to tie these to her most tomboyish character - through modern eyes, it's hard not to read Tom as trans - and I wonder what that meant, consciously or otherwise.
Something which perplexed me in Oberland and I'm fairly sure crops up elsewhere in the series, too, was a surprisingly detailed comment on the spacing of children (in this instance, Joey's, but I'm sure I've read similar comment elsewhere on Madge's), as though it was deliberate and well-planned. Is she actually saying that Joey and/or Jack were consciously practising some method of family planning, or is this just random ramblings in the same vein as Joey expressing a wish for twins/singletons/quads of precise genders (and probably hair colour)?
And, indeed, just in case we get too much to thinking that she is actually being very serious and sophisticated about all of it, suddenly a quick burst of the Red Sarafan saves a life and all these serious thoughts fall back to earth with a bump. 
Increasingly though, I'm not sure whether she really did want to 'be' Joey. I think she's besotted with her in a way I can't quite comprehend and which completely clouds her judgment and means Bad Things can never happen to Jo, sure, but I think I see Miss Annersley as the person she wished she could have been.
