Ok, but is is your point of view. For me working in new bath is a madness. I have crosses even in such a things like fitting the sink or loo and then
tile around which is really ridicoules. It is not the same as wall and floor tiles, becouse in this case it is easier to cut floor
tile and then cover it by bottom cut but you do not need to cut a bath. Bath is straight
tile surface is flat as well it match and it is small bead of Silicon, maybe wider than 2 mm but still very neat. It is all about to not work inside the bath and got same wide of bath edges which looks symmetrically. Do how you like to do but please do not try to convince my that my way is wrong. Bathrooms are usually small so i got even more work space all the time and then bath at the end all i need to do is a Silicon.
