   - It can slow down things significantly, because code is being executed
   browser side. Some code parses the entire DOM of the HTML document and do
   things with it. Some code polls remote servers constantly for information,
   - It can be a vector for security attacks (Cross Site Scripting).
   - It can be a hindrance to accessibility.
   - It can be an obstacle to content getting properly indexed in search

It is bad design to make it mandatory. Optimal case is to make it enhance
the user experience (AJAX for lookups, type in a few letters and a list
comes down and you can pick, ...etc.), but also make it degrade gracefully.
By this, I mean that you get a site that is still usable, but perhaps not as
convenient as the javascript version.

Google's Gmail for example has an HTML version. Yahoo's Mail claims that you
can use Classic without Javascript, but you still have to enable Javascript.
Bad design.

The issue is to make such features mandatory, and not degrade gracefully.
