I was wrong. I’m sorry. I was too cautious. I’ve been too thoughtless.
The requirement to change the name after modification seems to be a perl license requirement.

While it may be included in a Perl license, the “name change” requirement in my legal statements came about independently because some people were making changes to my TiddlyTools add-ons that resulted in errors or other differences in function or behavior.
When people subsequently copied those modified versions of my add-ons and then encountered problems, I would receive “bug reports” that were not reproducible by me, since my original code did not include the modifications.
I would often expend a great deal of time and effort trying to determine the cause of the reported problem, only to later learn that it was due to someone else’s changes to the code, for which I should not be held responsible.
Requiring a name change for modified add-ons ensures that particular situation can be quickly recognized and I can then direct the reporting individual to contact the person who made those changes.

I support this name change requirment and it is even good for private wikis that will never see the public internet to help when a published plugin is upgraded and we want to update it. Sometimes it is best to apply changes to someones plugin in a private wiki rather than make it look like the original plugin.
