@olivermrbl would love to have a talk w/ @adrien2p about this before merging since he probably has opinions here 😉

adding blocked label for now

[olivermrbl]

Sure, can I get you to add in the PR description, what you would like to discuss?

Requires different reviewer approval.

Would it be possible to include benchmarks of the effect of these changes?

[adrien2p]

LGTM, good work 💪

[adrien2p]

Would it be possible to include benchmarks of the effect of these changes?

The benchmark won't show much, but we go from 600 queries to 1 query instead, which has quite of an impact, instead of having the numbers of queries growing in correlation of the number of variants, it is constant :)
