The current TAA also removes most small, moving details like raindrops outside and on the plane’s windows, so in that case it even loses image quality.

I agree and it is even unbearable in VR regarding road traffic (see videos):

However if I understand this correctly, FSR is a post-process scaling technique post TAA. If this is the case, any TAA artifacts won’t magically disappear with FSR either and could be exemplified instead.
