VHF/UHF beacons on FT8?

It seems to me to be a "good idea" if all beacons had an FT8 transmission slot. A single FT8 TX slot is only 15 seconds, but this would allow monitoring of beacons at great range.

For those not equipped for FT8 there could still be a CW slot. All the beacons in a region could co-exist in a few kilohertz of band which beacon hunters could monitor all the time.

WSPR is too long at 2 minute transmission cycles, but FT8 would be far better. Shorter TX slots would make monitoring by modes like aircraft and other types of scatter more probable.

On reflection, maybe all beacons including HF ones need an FT8 slot?
