Hi Dan,

a comment from my side. Nothing precluding the draft to progress but having the m value in the label make me thinking.

I know there was lots of discussion in the past and likely the result is somewhat described section 4.2 however the use case I have in mind is when an established flex-lsp (hence a w/ flexgrid labels)  needs to be enlarged/shrinked. This operation implies a label value change. 

Now, does this consideration needs room in this draft /within framework /nowhere? I don’t have strong opinion just throwing a doubt on the table.
