In what way? Either there is a need for variants, or there is no need for variants but it is perfectly okay to make them, or there is no need and it's not okay to make them.
If there is a need, then they should be made.
If there is no need, then they can still be made (maybe even revealing a new need in the process).
I guess it seems like a non-issue to me.
Then again, applying my own reasoning:
There is no need to ask this question, but it's fine to ask it anyways.
