I feel sure that for the present, at least, there can't be that many differences between Mos & AmigaOS4 for software to be written for either, or for both.
Could not Applications, Services, and Games, for BOTH Platforms be marketed on just ONE CD with individual Installers to be able to install just the particular components required for running on either system?
For instance, in the past there have been cases of the ONE MEDIA containing TWO versions of a piece of software: like the game Blasteroids ( 1987 TENGEN. 1989 MIRRORSOFT Ltd.) which was marketed on a 3.5" diskette as DUAL FORMAT for PC & COMPATIBLES/CBM AMIGA.
Surely if THAT could work, a media could contain DUAL FORMAT MOS/AOS4 install versions?
:-?
