ok. works for me. Seems like a good idea to have such optimizations in a project of this size.

 * Did you perform an exploratory manual test run of the code change and any related functionality?

nothing really changed. tests still passing

 * Did CI run pass? If not, please explain why.

yes

 * Did you make sure that the branch does not contain spurious tags?

yes
