It being the .local/share/baloo directory?

Not necessarily. As you say, there are 2 population groups who could complain about the default settings, and one of those is likely to be perfectly capable of following tuning instructions.
So, if you can write an algorithm that keeps track of actual usage and then provide sensible settings from that, those power users can edit their .cnf file to copy the tuned values.
It would be just as possible to do this through the akonadi bootstrap routine; you probably already have a .cnf template somewhere, in which you could easily replace certain hardcoded default values with a token that gets replaced by a tuned value. Personally I'd want to be really sure that those tuned values are sensible though, before allowing automatic hacking of my configuration file (which might contain other tweaks of my own).

Recent regression or long-standing bug (since 4.1x)?

Side-ways related: does email search/indexing still work on platforms where Baloo itself no longer works (AFAIK anything other than Linux)?
I already see a reduced functionality in email search (presumably rather in the indexing) in KDE PIM 4.13 and 4.14 on OS X w.r.t. Linux, and 4.1x Baloo still works as intended otherwise on OS X. It'd be a pity not to have any search functionality - if KDE PIM 5 has the objective of being cross-platform of course.
