This is #13, but happy to leave this open. It's tricky since it will require extra information in the index and a new index format. Definitely something we want to address I think.

[marxin]

Maybe you can sneak in a few bits in the current index format. What do you think? Is the problem related only to the executable flag, or the flags as well?

[peterwaller-arm]

It's all of the mode bits. Yes, I think the information can be put in there in principle, with effort. Can't promise a timescale at the moment, apologies.

[peterwaller-arm]

I have a draft PR to implement this at #107.

This should be fixed on master and we're preparing to make a release before too long, sorry for the wait, it has been a spare time project :)
