The most likely scenario is: edit, read, edit, read (repeat N times), publish the page, read it again, find a mistake, no way to fix it unless deleting the page and paying again.
It's weird this is an issue. I don't think I ever edited a page when I posted on a blog and I maintain a couple WordPress blogs for businesses and associations and they never update posts after they've published either. I don't think it's as uncommon as you think, that or maybe people need to proofread before publishing?
I don't think "issue" is the right term. It's a caveat and as long as it's displayed visibly (it is) it's fine.
But JFTR, I think I've edited around 50% of all blog posts I've written in the last 10 years at least once. And not only because of typos. Some people might need to change their workflow.
Uh... okay.
