Not really. The line was removed in the first place not to change Boba’s character or lore, but because the scene just stops to take a detour to give exposition about a character the audience is familiar with but has no bearing on what’s happening.

I think the audience would have no trouble at all inferring he’s a clone or accepting when this is more or less stated in new content.

Also, without the line specially stating he is completely unaltered and genetically identical, it makes for an easier time head-canon-ing that even in Boba’s case he still ages somewhat faster than his host.
