PSA: "Generation History" retains ALL variations generated from generative tools

I found this discovery fairly alarming: after using generative features, Illustrator retains every single variation of generated vectors within the file. As far as I can tell, these aren't visible anywhere except for the "generation history" tool panel, which I've never opened. 


I had a pretty simple file that I discovered had 100 variations saved within it. These were the results of me experimenting with some of the new generative features in an earlier version of the file. I had deleted all of the generated vectors awhile ago but kept working within the same document, and I also copied the doc and used it to create other, separate files for this same project. I just recently exported a ton of final assets from these files and delivered them to a client. ALL OF THESE INDIVIDUAL ASSETS INCLUDE THE FULL GENERATION HISTORY. Which means that my client (and whoever else receives any of the files) can see all of these unintended working experiments, but it's also significantly bloating the file sizes, adding ghost fonts to the files, and I'm sure contributing to the already laggy performance of recent Illustrator versions. 


After deleting all of the variations from this example, the file went from ~7mb to 1.8mb, and the same goes for all of the many final assets I already delivered to my client; files that should be less than 1mb are significantly larger and they are likely to cause issues whenever they wind up in production for printing etc.


I will now be going back and spending a significant amount of time purging the variation histories and re-exporting all of these various assets and then resending to my client. I find this totally bonkers; at the very least, there should be some kind of warning dialog when saving that notifies you of the un-purged generative history.
