JacobiSVD: thin U and V are only available when your matrix has a dynamic number of columns.

Hi,

As the title says, there is an interesting assertion inside JacobiSVD (which I accidently triggered): JacobiSVD: thin U and V are only available when your matrix has a dynamic number of columns.

It was introduced in commit 8f0e80fe (that's over 10 years ago!).

What's the reason why thinU and thinV are only available when the number of columns is dynamic?

Considering that this assertion is over 10 years old, I can imagine that there were good reasons for it but have been fixed / improved in the meantime?
