install-missing-packages installs all flavours

Hi,
I am building some lightly customised install media for work and am trying to avoid having to build all the packages myself (to save time) so normally I create a metaport with RUN_DEPENDS on all I want then run 'make install-missing-packages' to fetch all of the prebuilt packages.

This seemed to work fairly well until recently when I tried it, but now it pulls in all of the port flavours which obviously blows out the install size to a ridiculous degree.

For now I modified my install like so:

--- /usr/ports/Mk/bsd.port.mk.orig      2022-08-12 09:33:02.669922000 +0000
+++ /usr/ports/Mk/bsd.port.mk   2022-08-12 09:33:03.553032000 +0000

Which works a lot better for my use case but I am not sure if it's a general solution or not (or if there should be a 'install-missing-package-flavours' target or something).

Curiously I still end up with Python 3.8 and 3.10 but I can't see where they are being pulled in. I ran this to calculate the deps:
(for i in $(make -V _UNIFIED_DEPENDS); do
echo "============ $i"
/usr/bin/env PORTSDIR="/usr/ports" dp_MAKE="make" dp_PKGNAME="gs-ports-minimal-1.0" dp_PKG_INFO="/usr/local/sbin/pkg-static info -g" dp_SCRIPTSDIR="/usr/ports/Mk/Scripts" dp_OVERLAYS="" /bin/sh /usr/ports/Mk/Scripts/depends-list.sh -f -m "$i"
echo
done)|less

(Ran in my meta port) 

However it only shows Python 3.9 (as I would expect) but 'make install-missing-packages' still pulls in 3.8 and 3.10. This isn't a big deal since just those ports are pretty small but it seems like a bug.

Thanks.
