Historically using CC by-SA for the tiles had a certain logic, as the
data used that licence and while there was a cloud of uncertainty how
that would apply to OSM data, you could reasonably argue that the tiles
were a derivative and had to be licensed on the same terms.
Post licence change that tight linkage has gone and the creator of a
"Produced Work" has a large degree of freedom in how to license their
work. It would, for example, be completely possible to take the CC0
licensed openstreetmap-carto style sheet and produce -exactly- the same
tiles as the standard layer and license them differently. Or are we
claiming that we are actually licensing the design/look and feel of the
standard tiles on CC by-SA terms (and by that have rights in any
derivatives of that style) and you can't actually use
openstreetmap-carto style sheet to produce a style that is visually
similar to our standard style?
Unlikely, so why are we are applying a licence that has a number of
undesirable properties and would cause a lot of headaches if taken
seriously to our tiles?
