There are other benefits to the B
In my case, I play a lot of ghost notes and in most cases, it’s a fretted note where I pull off the fret. My technique for ghosts is harder to do on an open string; so if I’m ghosting a low E, I can fret it.
The B is handy when you use the low notes before your target note; for example- Ab down to F on the E string; quite often I will approach those notes from the V below them.
Let’s say... a quick low C before hitting F.
Also, a fiver gives you a larger mass of wood which may contribute to neck stiffness/sustain/dead spots.
