Does Pharo have ScaledDecimal and it is used? it ha but I do not know if this is used.
If so, that would be the biggest piece that would be removed. There wouldn't be any serious bugs that would cause major trouble otherwise.
I can help you after school gets out in a week. I need to
do a quick count of how many lines of code need to be fixed in squeak for submission to SFLC. I can do the same for Pharo. I don't know how strenuous you want to be in your license conversion.
What is the reason for Pharo to go with SFLC?
I do not know.
You should chat with Randal Schwartz about what you need to decide before you can start relicensing, and what you need to document in case your relicense needs to be reviewed in the future. Yoshiki and Juan did not do this and thus we have no evidence yet that Yoshiki's relicense is strong enough.
There will be no such evidence. There will be no evidence for a statement like "there is no white crow".
Indeed I think that we should stop somewhere.
