I have no problem with the feature but what bothers me here is the addition of a launch argument.

Anybody here can comment ? Any alternative to a new argument ? Any idea for making its name more obvious ?

For my use case, I would actually prefer it to have it by default. I added the flag just for not changing the existing behavior.

Given that nobody commented, I suggest you change the PR by removing the additional argument, making it delete the file by default, and we'll see what we do if somebody files an issue for regression.
