I would assume: no.

Given all these observations, I think it would make sense to take the XSLT
approach first (add an XSLT-generated ID if non exists) and then gather
experience with this approach. This is easy to implement and can be extended
later if we see the need.

As I've heard no objections to my proposal from Monday, yet, I'll process
Jost's patch (as is) tomorrow morning (my local time) into a branch off the IF
branch. From there, we can take it further and incorporate all the feedback.
That also makes it easier to track what is changed.
