ARCH restriction for port of closed-source Linux software, looking for opinions

Case in question is, once again, multimedia/makemkv.

For a long time, the distfiles contained binaries of the closed-source
part for amd64 and i386 only, so naturally, the port had

ONLY_FOR_ARCHS=		amd64 i386

Now, upstream started adding binaries for armv7 and aarch64. From these,
Linuxulator is only available on aarch64. Therefore the variable now
looks like this:

ONLY_FOR_ARCHS=		aarch64 amd64 i386

This is, of course, exactly the default that USES=linux would set
anyways. Now I'm unsure whether I should just drop it and go with the
default?

Pro: It's actually the availability of Linuxulator that results in the
narrowest restriction now.

Con: The upstream software *is* restricted regarding ARCHs and maybe
this should stay being reflected.

What would you think is the better way to go?

Cheers, Felix
