This is part of the standard behavior of 'read', e.g. section 4.3.5 of
the R6RS, and has been for over 50 years.  Lots of existing code assumes
this.  Changing it now is out of the question.

Also, the subject of this thread is misleading, because your proposal
would not make these reader abbreviations hygienic.

Not when some arbitrary code looks at the result of 'read', or inside a
quoted datum like '(nested quote 'x).
