Yep, that's one issue with it.

What I did for Bate Bate, in Cronulla, NSW was to split into sections and

Which is what I was thinking, with the other option being delete the name
from the full beach & just add named beach nodes to each separate area.

There are other possible solutions with multipolygons or relations,

Scary stuff! :-)

That may be the neatest way - just delete the whole thing & re-do it all.

In iD you can add nodes along the way and split it, unfortunately iD tries

I've given it a go by doing this & you're right, it's messy with hiding
boundaries, then un-hiding them so you can fix the alignment. I'll check to
see how it looks tomorrow after things have updated & find out if I've
broken anything! The delete & re-do is certainly sounding the easiest way
