Even for a dev 68k offers advantages because much more development options including lots of optimized compilers. Free Pascal f.e. also works on 68k, of course you need lots of horsepower. There is also no reason why in future even modern software should be ported to it.
What 68k lacks is proper SDK. To develop for 68k you have to collect it from the pieces. Get NDK from one place, compiler from another place, then download various standard linklibs (z, png, etc.) to get started. And finally download extra header files from yet another place to get an access to bsdsocket.library and other "standard" stuff but you might still found out that there is nowhere stdint.h, there are N+1 ixemul implementations all incompatible and everything else is in abandonded state.
I'd like to port some software from MorphOS to 68k, like Snoopium, but it always takes too much time to get all pieces together and it never gets done.
