Never fear BletchMAME will be supporting software lists, and I would agree that they are the way to preserve these myriad console and computer software in the same way we are preserving arcade systems.

That said, the softlist approach is a bit more alien for the computer emulation world, much of which is probably not in “the” scene (or rather the “emu scene”) that wants unimpeded use of the dumps they personally made (that might be “bad” because they have the saved games they made as a twelve year old), and that will be taken into account.
