But my argument is about interoperability between implementations, e.g.
reading with Scheme implementation A code written by Scheme implementation B.

I fear that is a lost cause.  Of 22 Schemes that I tested, only 8 support keywords at all.  (Racket has something it calls keywords, but they are not self-evaluating or even expressions at all: only quoted keywords are expressions. They use SRFI 88 syntax.)

Each of the :foo and foo: styles are supported by most of the 9, whereas the SRFI-88 style was supported by only 4.  See for details
