I do understand where the thinking comes from, though.

1) Pages should be more responsive than the 1990s-style CGI model,
where every action is a link or button click that completely replaces
the current page.
2) Many actions therefore must be implemented using JavaScript, an
AJAX call (if necessary), and DOM manipulation to change just the
parts of the page that need to be changed.
3) This means that the entire content of the page must be under JS
control, and the entire "user-accessible" part of the back end should
be returning JSON, since that's what #2 requires.
4) If everything has to be under JS control, why not just send out a
stub to start with, and begin everything with an AJAX call? That way,
we don't need to maintain two of everything!

The logic is reasonable. Deduplication is valuable. But the result is
a web site that has a stubby splash screen until the back end
responds, and that's why I call it merely "unideal" rather than "evil
spawn &c".

Oh yes, I do not miss those days! And it was compounded by browsers
that, when they started receiving a <table> tag, drew nothing
whatsoever until they received the </table> and could lay the whole
thing out. Add to that slow internet connections, so it would likely
be some seconds or even a minute or more before the </table> arrives,
and you have a perfect recipe for frustration.

But no web site these days would ever make you wait for its contents.
'Course not.
