If your arse is hanging over the line, I'll ask nicely if you can move forward. I'm not being a Sky God or Prima Donna
, just don't want to do a "United" like in MEL.
Those taxiways can hold an A320 or 737 easily -
if the nose is at the hold line.
Holding short 16R at B2 is the interesting one though, no hold line at Taxiway B so I won't taxi behind you there!
