I agree. Having a bip number, literally means that, you have a bip number. Bip editors are't there to decide what have and what doesn't have consensus.
The only thing I don't like about the bips repo is the weird numbering. But that's just my OCD talking 😂

God how I hate banks. I can't wait to a world where I don't need to have anything to do with them
They made me, and my 90 years old grandpa wait for two hours, to fix something that were their mistake in the first place. It's the third time, and this is for him to take my decease grandmother's pension (here in Brazil if your spouse is retired and dies, you receive their pension for as long as you live).
It's already a heart breaking situation, since he lost the woman he lived with for 70 years (I know, impressive). Why they need to make it harder?????
It's not the only time where he had to waste hours in line for bureaucracy sake.

A friend sent me, sharing with y'all
Happy 45²
2025 = 45² is a "perfect-square year."
It is represented by the square of the sum of all digits in the decimal number system.
(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)² = 2025.
It also represents the sum of the cubes of all digits in the decimal number system.
(0³ + 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³) = 2025.
The last "perfect-square year" occurred in 1936, and after 2025, it will only happen again in 2116.
Happy 45² to all of us!!!
An excellent 2025 to you!!!

They can't, because they assume that nonces are:
- The very last thing in a 80 bytes digesg
- Binary (nostr uses strings)
Even if you make the nonce come at fhe end, and precompute the midstate for the first block. You still need to have a closing "] to make the json valid. While you could do accieve the latter by fixing the nonce range to keep the last bits fixed, you lose a lot of nonce space.
And again, your serialized note should be exactly 80 bytes
