In addition, it is a semantically distinct character akin to 212F
(script small e,
natural exponent) but is no easier to decompose (<narrow> does not necessarily
mean "in monospace font: halfwidth").

The environments in which it occurred were predominantly monospaced
(mainframe computing) with restricted string length (punchcards, drum

Sure. E.g. a Soviet or German equivalent of a punchcard coding form a
la http://www.answers.com/topic/fortrancodingform-png-1 for coding in
or preparing numerical data (I have used a Soviet equivalent myself).

It's the latter. Are you saying that only they would have the
authority to request this character?
