Bad idea.

> "license"

Both useless.

> "datadir"
> "userdatadir"
> "homedir"
> "configdir"
> "cachedir"
> "datadir_list"

All mostly useless and bad ideas, c.f. other post.

> "action_id"

Same as for the MacOS UI: this should not be exposed.

> Those, I do not know:
> "mdate"

Useless in an extension. The only reported use was to reimplement msleep() 
with mdate() and mwait(), which was stupid.

> "mwait"

Mostly harmless but mostly only used for shitty polling code
-> bad idea.

> "lock_and_wait"

Will probably crash.

> "timer"

Same as mwait() -> bad idea.

> Those seems wrong to expose outside of intf:
> "should_die"

Will crash.

> "quit"

Not extension business -> bad idea.

> Opinions?

My opinion is that none of these should be exposed outside interfaces.
