TOS v1.04 works fine for me, e.g. in 960x608@4 and 1920x1200@1
resolutions which are nearly 300kB.

If you want to propose that to be changed, you need to debug
why GEM apps crash at >300KB sizes and provide a Hatari workaround
for it.

Instead of VDI mode on TT, you can use Falcon emulation
and standard Atari tools for setting larger 256-color
resolution.

--machine falcon --dsp none --fpu internal --cpuclock 32
