they may work great for you and if so congradulations.
some farmers may welcome beans like these but there are many that would be ticked if they find many herms that they didnt know would be lurking in the genes, i would caution letting people who may grow or spread these know especialy in this case where its happening all on its own without stress.
even 1 pollen sac can pollinate a plant even if for only a few seeds, the plant will stop focusing on flower and resin production and start focusing on developing the seeds and if it pollinates any plants next to it the same will happen and if your running staggered flowering stages or SOG type setup this could throw a real wrench in the mix.
maybe you only find 1 sac out of 6 clones but another growers climate could bring out the sacs in droves and also the subsequent generations could be more prone to this happening and severity of it wouldnt necessarily be the same as the mother when it does happen it could throw many more sacs.
in my eyes thats anything but stable, it may be potent and may produce no true males and if thats all your after than it could be great for you but for many it can be very troublesome
