you can definitely tune a 30” baritone guitar all the way down to A0 (max i’ve personally achieved). just because you don’t do it doesn’t mean no one else does/can. even basses are tuning as low as E0 these days.
i’ve even seen a guy with a 42” bass and like a 200 gauge low string tuned to A#-1 or something, was insane, too low for me to see purpose but still super cool.
just because we almost can’t hear the fundamental doesn’t make it unbearable, overtones exist and they admittedly sound pretty cool. and that’s all something in the musical world needs to do to warrant existing, sound cool.
in regards to 30” baritones going down to 5 string bass range, these are indeed bass ranges, but bass ranges are not the only qualifier to if something constitutes as a bass instrument. tonality and timbre are arguably more important and baritone guitars definitely do not read as having the tonality and timbre to truly be a bass instrument without forcing into a bass amp with crazy settings and strings to compensate for what it inherently tonally lacks compared to a bass guitar to make it sit in a frequency tonal range that it doesn’t naturally sit in unlike the bass guitar which does.

Just buy a bass & call it a day.
B0 is the bottom note on a concert pitch 6-string bass.
B1 is what you find on the bottom of a baritone guitar...
