no, that is overkill, but what can be done is:

\startbuffer
the label
\stopbuffer

\externalfigure[buffer][factor=max]

or

\scale[factor=max]{\framed[align=normal]{the label text}}
 
that would scale each label to fit best

but it would look funny (all those different sizes)

a more clever solution would choose different sizes for different label 
components depending on the result

(there is a rudimentary strategy mechanism, one day i will perfect that, 
which can be used to optimize whole documents, think of manipulating the 
distance in columns, or fontsizes in order to stick within a certain 
amount of pages; pretty old and rusty code btw)
