Hm. Shouldn't it be possible to work around this restriction with 
something in the line of:

\version "2.19.49"

\paper {
  indent =
  #(let* ((layout '()) ;; <=== How to get the default layout here?!
          (text-props (ly:output-def-lookup layout 'text-font-defaults))
          (stil (ly:text-interface::interpret-markup layout text-props 
(markup "Supercalifragilisticexpialidocious")))
          (xext (ly:stencil-extent stil X))
          (width (- (cdr xext) (car xext))))
    width)
}

\new Staff \with {
  instrumentName = "Supercalifragilisticexpialidocious"
} { c'1 \break c'1 }

The goal being to adjust the indent to fit the largest instrumentName 
(manually selected and entered before any content is inserted). The 
above code will not work, though, because I don't know how to get some 
layout object at this point...
Any hints?
