I'm guessing you have never tried these things but image based Smalltalk implementations have supported VCS for decades now, literally. In Pharo this is with git using Iceberg:

They even wrote a tutorial to make it easier: https://github.com/pharo-vcs/iceberg/wiki/Tutorial
It's not magic, it's not even a problem, because the problem you're imagining doesn't actually exist. So long as the user of the system has at least half a brain (and maybe less) they will be capable of distributing their code with git these days.
I will not agree, and I hope you will understand why after I give some evidence. Here's what Pharo advocates typically point people towards:
https://mooc.pharo.org/#week1 - I've linked to the week1 anchor so you can see that Iceberg makes it in pretty early. I hope you understand that despite your hopes for me I cannot agree. Sorry to crush your hopes, I hope you can forgive me.
Honestly, I don't have the slightest idea what's going on with you.
I was having fun with the word "hope" which I find to be a weird sentiment because it expresses a lack of agency or control over a situation. But you didn't lack agency or control, you had an opportunity to persuade. An opportunity to convince me of your position and to try and bring me into agreement, but you didn't use that opportunity. It would have made more sense to me to express a hope for agreement if you had at least taken the chance to provide evidence for your claim.
>> I hope you will agree that this is not how Smalltalk is usually advocated.
You offered no evidence, you just hoped (asserted a lack of control in persuading) that I would agree with a bald assertion. I offered evidence to the contrary, the Pharo MOOC, which turns up in most discussions I've seen, here and elsewhere, about Pharo in particular and Smalltalk in general. Interestingly, to me, you didn't even engage with my evidence, which is unsatisfying.
You could have responded to it. You could have provided your own counter-evidence. But you didn't.
