That's true, though one particular variable at hand is actually a
trinary.  The behaviour that we have historically had in OE, which seems
to capture most of the significant use-cases, is:

ONLINE_PACKAGE_MANAGEMENT="full" (or not set at all) means to install
opkg or whatever and all its metadata, like oe-core does now

ONLINE_PACKAGE_MANAGEMENT="none" means to not install opkg or its
metadata on the target at all;

ONLINE_PACKAGE_MANAGEMENT="add" means to install just enough package
management infrastructure to allow new packages to be added after the
fact, but not to allow packages that were shipped in the image to be
manipulated.  I think the main use case for this was language packs and
the like.

I'm not entirely sure that O_P_M="add" has ever actually worked properly
(I don't use it myself) but it doesn't seem like an entirely worthless
proposition.

I agree that TARGET_READONLY_ROOTFS or whatever could be done just as
well as some kind of FEATURE.
