I agree, many of the suggestions are fine - retaining online meetings and so on. But there is absolutely no need for them to have special powers to allow them to do that. Just bring forward the relevant legislation that says "meetings shall take place in person at x frequency" and make changes to it to allow online/ more flexible meetings! If it is indeed a good idea there will be limited parliamentary debate, maybe some improvement of any suggested wording and it's done...
Anything else that needs "emergency" action can be brought forward as it was in March 2020. Seeking to have certain powers indefinitely, that can be invoked without parliamentary debate and agreement, with minimal notice and for poorly defined reasons seems very iffy to me. Especially given there is precedent for them having been granted the powers relatively easily and quickly anyway, when they are actually seen to be warranted. Parliament isn't necessarily an obstructive thing, just putting barriers in the way of the SG, cos politics/ westminster/ tories... And that the SG seems to think it is is somewhat concerning (or reflective that often their proposals do need to be challenged!).
