If you 3D-print the replacement baffle, then you can reverse the modification at any time, only a few screws are involved.

Well you can't have it all: fast aperture, long range, great IQ, small size. The latter is the hardest to obtain. The 10mm difference at the wide end in particular makes the 60-250 much more useful, especially on FF, than a 70-200.

They will, it's written on the roadmap.

They might, though the specs for that lens might change as it's not named yet.
