Cultivar identification

Is it relatively futile to identify a cultivar via a rollitup forum thread with pics?

I'll take any answer off-the-air.

I have a new varietal that has a distinctive wide leaflet morphology that has made me insatiably curious.
Perhaps I'll post a "guess the morphology (& speculate on the rest) thread with pics.
So far, I know this new cultivar, like my current cultivar, is a hybrid.
haha.

I am seeing some genetic testing services resulting from my searches. Are those good enough, yet?

Last thought... Gosh I know there's lot to unpack here. Here's a big one.
When I speak to some serious breeders, I learned that sometimes they don't disclose every cross. Perhaps the idea is to avoid releasing proprietary info. I guess the logic is that somebody could reproduce their "custom" varietal. Is hiding a cross input a widespread behavior? If so, does that make any effort to identify a cultivar and for that matter seedfinder pretty much speculation and guessing? Hit me with the truth.

Randomly saw this post that kinda sorta addresses my gut feeling that everything is a hybrid... plus other useful terminology.
FWICT, this was posted to rollitup in 2018 and 2019.
Here's a 3rd instance for the post-pandemic era...

Pyhlos is a pretty cool idea. There's a vibe that they were going through choppy waters for some reason. Controversy perhaps. If anybody sees media with some form of info or testimony as to what Phylos was going thru, then I'd be interested.

That brings up another question. How can genetics be properly analyzed for identification purposes without the owner worrying about the genetics being "lifted" and propagated outside the lab?
