I'm afraid this has made no difference to the times I measure.
I checked that if I apply a diff to revert back to a single dir-locals
file, the times do indeed fall back to what they were originally.

If no-one else other than me notices this, perhaps you should forget
about it. (Again, these are the times for non-parallel debug bootstrap
builds.)

As a final comment, if the aim is just to override an existing
dir-locals files without modifying it, this can be done by direct
application of dir-locals-set-class-variables and
dir-locals-set-directory-class. The issue there is that the UI isn't as
convenient, and it completely replaces any dir-locals file rather than
appending+overriding it. But those things could presumably be improved.
