No, no , please no. FT8 is a 'QSO' mode and letting loose FT8 beacons in the FT8 sub-band is, in my view, pointless and counter-productive and not at all in line with the ethos of the mode. I find it hard enough to make any FT8 contacts now as the sub-band on 40/20m is so crowded (however FT8 on 6m in the Sp-E season was excellent).
