As a point of reference, Riseup has approximately the same number of
lists as you do, and performance with the patches is good. The crawling
the list configs multiple times was absolutely one of the main issues.

Its true that deviating from upstream standard code makes things more
difficult for upgrades, reducing those deltas is paramount for
sanity. However, the patchset that we have, we have forward ported for 6
different releases now, its not too difficult of work, and if you are
also using them, maybe we can both benefit from each other's efforts
here. So, if you do manage to port the patch to 6.1.7, please let us
know so we can include your port in the set we are maintaining in our it
repository!
