What does deprecate rather than require 1.2 mean? If a scientist asks, what
does the formal language specification state concerning the absolute need
for whitespace before and after a token, what is the answer?

Please don't say we deprecate (definition: earnestly disapprove of)
whitespace, that is just plain silly. In the specification a quoted string
is terminated by the first occurrence of the matching quote (1.2), or it is
terminated by a quote immediately followed by one or more whitespace (in
which case you are actually voting for 1.1).

Again (and again and again, how many times do I have to say this?)
deprecation has to do with an implementation. What are we specifying?

Same question, earnestly disapproving of a character set is not a
specification. What will be specified for the language? Is the , allowed or
not allowed in an unquoted string?
