No, my goal is that all new emacs frames, including the first one,
start out at a maximum height -- but my broader goal is to know what
that height is programatically. I do things at times like setting up
an elisp function to achieve a particular window layout, for example,
and knowing what the maximum height is comes in use there as well.

Not really. That will maximize the current frame only at the moment it
is executed, and it doesn't tell me in advance what the height (in
lines) is going to end up being.

What I want is to know (by calculation) what the maximum height, in
lines, happens to be so I can shove that in for 'height in
default-frame-alist. (There are other uses for such information of
course, see above.)
