I would make a fem line to preserve a clone only but tbh never thought much about it. Only auto I’ve ever grown was the first ones to hit the market years back and that was the Lowryder. I haven’t been too keen on them since but I have a buddy growing one now and though they’re not really my style... it does look pretty good.
I guess that’s not really an answer... but at this moment, no. But I like the usefulness of being able to feminize or make an S1 via STS of a clone only if no one had the cut or could take care of it and I knew I would miss the strain later on. But in all honesty, I’m really not so much for these kind of weird genetic tinkerings.
Why do you ask @legalcanada?
