That's the opposite issue, and it's definitely better to have a tenon a little too tight than too loose when new. Fixing that is much easier, assuming you have someone in your area who can do it.
It's mostly a consistency issue, but possibly also stability of the wood and weather in your area.
Some new clarinets are fine, no wobble and not too tight. Some are loose, but IME not that often. Some are tight, not rare at all.
It happens often enough that new clarinet tenons are tight that it's impossible to disassemble, or so much that it's impossible to assemble in the first place (most recent I saw was an RC Prestige where most joints couldn't be assembled all the way).
An extreme example I remember was a new E12F.
I always remove the least to allow the joint to be good, you never want to remove too much. I did that as usual, but quite a bit had to be removed.
In the next six months it had to come back two more times to remove more of the tenons.
I occasionally read that joints should be without wobble even without the cork. The above is an extreme case, but for all clarinets, at least here, if they were fitted that way when relatively col and dry, they would bind after playing. The change in a good and stable wood joint is more than to be able to allow that fit. Maybe weather in other areas allows it.
