@TylerHelmuth what I implemented is a bit of a hack :) You need to probably to have "flags_no_record_value" func that works with bool. Later we can add other funcs when multiple flags are added.

Ah ok, I thought this issue was only tracking the switch to the new fields. I'll probably hold off removing the hack until Flags is completely removed and FlagsStruct is gets renamed to Flags

Reviewing OTTL's use of flags today it looks like this issue can now be closed as we use Flags() during the GET (casted to int64) and SetFlags during the SET. Helper functions are no longer used.
