Newsflash: we're not talking about text properties in Emacs, which has
historically been hostile to both embedding in other apps and to FFIs,
and is not normally used as a network daemon, but instead is usually
controlled by the user who owns the resources Emacs manipulates, and
in most cases has little malice toward himself.

We're talking about text properties in Guile, which is designed for
embedding and and extension (including wrapping foreign functions).  A
Guile with text properties hasn't been written, let alone released
AFAIK.  I dunno about the "network daemon" part, but Mark mentioned
that as a target application area for Guile.

It would be "nice" and "efficient" for Guile to implement properties
natively so that Emacs could just use those, but Mark is correct to
worry that those properties would be used to bypass validation modules
written for pre-property Guile versions.
