1) how to configure OVMF to enable/disable lazy acceptance

2) how to introduce an automatic mode in the future where OVMF does the
right thing based on what the guest supports. Gerd floated the idea of
tying it to ExitBootServices as well, but not sure there's a solid
plan on what to do here yet.
If that's accurate, it seems like the only 'safe' option is to disable it via
#1 (accept-all), and then when #2 comes along, compile OVMF to just Do The
Right Thing.
Users who know their VMs implement lazy acceptance can force it on via
accept-all OVMF compile option.accept-min / accept-X I mean.
