So a ‘mutable property’ would be one that is unset by default?
My understanding is that immutable properties store default
values--such as a procedure to be applied when calculating
Stem.thickness or whatever, and immutable properties store the results
of calculations for a particular instance of a grob--for example, the
value obtained by applying the default procedure to a certain Stem.
These terms are defined here (a bit cryptically I think):

Cryptically indeed :-)
You'll note that each of the other properties you offset has a
default value in scm/define-grobs.scm
As a side note: I find it confusing that these are not to be found
in the IR.
But they are--for example,
http://lilypond.org/doc/v2.19/Documentation/internals/dynamiclinespanner
is built from the entry in scm/define-grobs.scm.
Where do I have my mind? …
Good night,
