Aliasing slaves → slave
Link to alias

Reason:

If there's several slaves, then there's at least one slave. Both tags mean the same thing and I don't think we don't need the plural version. But it happens often enough that it would be worth aliasing in order to prevent images from getting lost in there in future.

Considering you could look up slave+group or save+solo or whatever you want, yeah, I don't see a problem with this at all.

It's just like horns -> horn.
