One problem with this, which is an argument for replacing the udev rules
with simpler config files, is that there is no way to add local
persistent (across system upgrades) udev rules in OpenWrt.  Unless I
missed that as well...

OK, I could of course add a file in /lib/udev/rules.d and add the name
of that file in /etc/sysupgrade.conf, but that's a little more than
should be needed for a local blacklist override IMHO.

I believe a nice addition to the OpenWrt packaging would be a
modemmanager UCI file, with any configurable stuff like log level, local
blacklists etc. Making such settings survive a sysupgrade is essential.

Works perfectly, as expected.  I believe it's a good default, at least
for OpenWrt.  Right now, there is no install-base expecting current
behaviour.  And I don't think OpenWrt users want to edit any config
files outside /etc/config.  Defaulting to "--filter-policy=STRICT" will
reduce the need to do that.
