Is this because of the duration-log override? NoteHead #'duration-log for
Kievan notation should be a separate function that is not based on style (this
is what I propose in my patch).

Why can't we have commands \startKievan and \stopKievan that do all the
overrides simultaneously?
For example, the command \hideNotes groups together several overrides. I think
it would be a mistake to make \override NoteHead #'transparent also control
Dots and Stems by default. It's better to have a global command that groups
together all these overrides.

I think it's important to keep properties as separate as possible. For
example, take the command arpeggioParenthesisDashed. In theory, we could make
it such that arpeggio has a style property that'd set all these things, but
it's better to keep them as separate overrides to various parameters. Same for
easyHeadsOn, improvisationOn, and tabFullNotation. A command like \startKievan
or \kievanOn or whatever should work like this.
