No, this was issue 3748.

commit a7eb9033f29d35d110afd1730a238f5c50e00369

    Issue 3748: Allow assignments with property paths to use x.y.z = value 
syntax
    
    This is actually an embarrassing oversight in issue 2883: while it
    became possible to rewrite
    
        markup-system-spacing #'minimum-distance = #25
    as
        markup-system-spacing minimum-distance = #25
    
    it has been overlooked to allow for the obvious
    
        markup-system-spacing.minimum-distance = #25


This commit is indeed version 2.19.0, but there is also the cherry-picked

in 2.18.0.  So this oversight has been corrected in 2.18.0 already.

The new developments allow numbers into alist indexes, and actually
referencing individual alist members syntactically.  But the assignment
syntax for symbols as indexes (and symbol list arguments) was
established earlier.  I think that the old

drumPitchNames #'slap = #'slap

has worked for a long long time (quite earlier than 2.12).  But it's
quite underdocumented.  I think it caught me by surprise when I first
discovered it in the parser.
