Yes, but emulation is a very easy work around. There are even some open source emulators that allow commercial use without credit required and only require source code to stay open and post any changes made to the source code online. For most games, the default emulator will run like 90% of games perfectly fine and if proprietary code for porting to consoles is an issue, a compatibility layer can be written that isn’t open source can work around that.
Whats I am saying is, its such a low effort thing to do that shows the company honors and values their legacy content.
