Hacking Question Updated from 6.0.1 to 9.0.1 and burnt fuses. Should I do another NAND backup?

[TehCheez]

Purchased my Switch used with 6.0.1 so I never had any fear of accidentally booting to stock FW since the fuses were already burnt. Decided to install my Trinket M0 internally and use the RCM strap before updating to 9.0.1

As my luck would have it, while testing my Trinket after updating to 9.0.1 my piss poor solder job caused the RCM strap to pop off without me knowing and I booted to stock FW. Wasn't using AutoRCM since I THOUGHT I had it at a hardware level.

With that being said, should I do a 9.0.1 NAND backup since my fuses are now blown or am I still safe with my 6.0.1 backup?

Personally I would do make a new NAND backup.
From what I read it's much easier to restore the NAND if the fuse count matches.
