Why would forbidding to write the file back remove anything?

> But I’m currently doing some refactoring and will consider how feasible it is to at least have a read-only mode that disallows the built-in mutating actions; the problem here is only that such mode is rarely used so I don’t want hundreds of actions to have special code to test for read-only mode, hence only if the impact on code can be minimal would I want to support this.

Well … how many subroutines are there in TM2 that write a file from memory back to the medium it was read from?  Hardly more than one; my mileage may vary.  But if so, and if that one would look at some r/o flag of the file in question and just not do anything if TRUE I’d be completely happy … I think.
