Nobody said that it wouldn't be possible to open or edit old files. The 
problem here is appearance.
If you open a layerer composite in linear space it will look different 
than the same composite blended in gamma space.
Some blending modes look almost the same, some of them don't. It also 
depends on the image. The effects of linear compositing would be more 
visible in some cases and almos unnoticeable in others.
So, what I proposed was just using linear space for blending for 
everything (including old files) and offering an optional projection or 
"bake" mode for keeping the old appearance as close as possible. And 
that can come later.
It seems pointless to keep legacy code to take care of the old stuff and 
complicate things just to be able to manage a handful of old files.

I think I can consider myself a high end GIMP user and not a kiddy doing 
animated signatures. I'm discussing about making GIMP a high end tool, 
which probably involves in some point getting rid of the low-end legacy.
It's a compromise, sure. But nothing keeps GIMP from getting a mechanism 
for importing and displaying legacy files later, on top of a sane and 
high-end pipeline.
