spontaneous, my guess about your question - and it is a guess and I have been flamed for saying it by trans people so no doubt will again is this.
Up to recently the ONLY people who were able to transition did so medically with full approval of medicine after extensive psychological profiling and with other options for what to do instead of such a radical change of life considered first.
Many others wanted to transition but for various reasons were not assisted. There was about a 90% drop out rate. So only 100 or so medically transitioned per year and 1000 others were deterred.
Some because they wavered or changed their minds. Some because they had no clear signs of dysphoria and it was thought they were really just gay. Some possibly had other problems either masking their gender confusion or caused by it and doctors did not think they were psychologically stable enough to change permanently.
Either way there was a weeding out process that meant only those for whom it was a necessity for survival day to day got through the net and the others bumbled on with life in whatever way they could.
There has to be at least some overlap between that group who did not get through the evaluation and those who now want access to the GRA by removing the gatekeeping that in the past seems to have been there to deter many of them.
Are all of these people trans? Or the same kind of trans? Medical transition is clearly only suited to a small percentage, but does that matter that many others want to legally change without that step?
These are the questions we are confronting.
But the differences are real, either in degree or basis of the dysphoria v lack of dysyphoria and other reason for wanting transition.
So if there are to be expected changes in how trans people behave or treat women has to be seen as a consequence of reasons for transition - which to me look to be the thing that is most changing right now.
