I don't think that would be an appreciable problem.

Shadow tiddlers are just tiddlers that are packed into a plugin. You can
create an upgrader module as a standalone tiddler, or you can choose to
pack it into a plugin. Using a plugin is largely a matter of ease of
distribution.

There's no user interface for switching upgraders on and off, but you could
write the module such that its behaviour is controlled by configuration
tiddlers.

Best wishes
