Booting expandable braid harness

Does it make sense to boot the connector onto the expandable braid sheeting if it will not be watertight anyways because of sheeting itself being porous?

I never have, though I have considered it a few times just for aesthetic reasons.

If it will make the particular harness look better in that install, go for it, if not, I wouldn't worry about it.

That being said, a boot can also provide some strain relief, so that would be another reason to consider it for some connections.
