I can't help but think I must be doing something really stupid here.

Without the patch it appears to import all the routes other
than the device routes marked
interfaces redundancy protocols that
do not waste IP addresses (e.g. do not use IP addresses for the
native interfaces). One problem with VRRP is that it is allegedly
patent encumbered.

your BGP design is wrong or you are
using the wrong solution for the job.
Complete guess: are you trying to survive when your AS becomes
partitioned? If so, the easy way (given you say provider)
is simply to carry around an IGP or BGP default route pointing
at said provider.

connected and interface routes an option? (this also has the
advantage I don't need to reconfigure bird when adding/removing
routes).

that if you are writing a

come in as RTS_INHERIT (not obvious that 'INHERIT' means 'KERNEL',
an RTS_KERNEL synonym would be nice).
