OK, here i'm silently presuming that GIMP is fed with absolute
color data (meaning that the device color profile is known in case
device dependend colors are

You don't need to worry that the sRGB gamut is rather small since,

That sounds good in theory, but there will be some very sharp

Regarding BABL: i've had a look at extensions/CIE.c and found conversion
routines
using linear light RGB with the sRGB primaries and white point -- that is
scRGB.
Everything fine here.
Now i'm not familier with BABL

I open up an image to make a small change to one corner. Why did other

Well, that's certainly true. Though open/edit/save,

Note that this is not true if you exceed the gamut of these two spaces,
and the resulting device values are clipped to the range 0 - 1.
