satchit, the same thing happened to me. I used an easy out, but I wish I’d some of these other tricks to try first.
No George , I did not sell them because of the screws in the reservoirs , I sold them because loss of tire pressure......

Well, I tried multiple options...
Removed the other screw and tried wiggling the cover - No movement.
Tried the rubber band - Gouged out more.
Tried hammering in a slotted screwdriver and twisting - It looked like the small screwdriver would break.
I took it to a local bike shop here (incidentally the same guys who last bled the brakes in 2018). The mechanic wasn't confident he could drill it without damaging the threads. The suggestion was to get a replacement reservoir just in case this one gets damaged.
Does anyone know if either 45510-MGH-641 or 45510-MGH-305 would work? Revzilla says that 305 won't fit a 2014. I'm hoping I can find a used assembly.

Not yet. Will try and get a spare reservoir first. The mechanic was worried that the extractor may damage the threads.

I would still FIRST try the left handed screw removal tool before spending money on a new/used reservoir , start with the smallest first and than go up if needed . The set will come handy for other screwy problems.

OK, kinda late to the party, but people have had good luck with with a fine grit on the head of the driver. Valve grinding compound. Some toothpastes. Bigger the screw head, coarser the grit you can use.
Scraping some grit off a 400 sandpaper may be a better choice for you in your case.
The sharp little rocks will lock in between the driver and the screw head.

Not sure what your mechanic was thinking about, but if you drill the head out you will not touch the threads. it will just take the top of the screw off and leave the shank in place which you remove after you take the reservoir top off.
