The 27 character limit isn't really a hash format limitation, but a
limitation of John's NT format implementation, ist that correct?

So, it would be possible to drop that limit (or change the limit from
currently 27 characters to, say, 54 characters).
But trying password candidates that are longer than 27 characters would
reduce the cracking speed to about half the speed of the current

Does hashcat also have a 27 character limit for NT format?
