-git: Why is drivers/net/wan/hdlc_generic.c:hdlc_setup() exported?

Commit 4a31e348e3ecaf54c50240109ac4574b180f8840 added an 
EXPORT_SYMBOL(hdlc_setup) with the justification
   hdlc_setup() is now EXPORTed as per David's request.

Is a usage of this export pending for the near future or could this 
export be reverted until a user is submitted for inclusion?

TIA
Adrian
