Has that been considered for inclusion?

javascript.options.baselinejit.content
javascript.options.ion.content

Set to false harden the browser and may cause problems with heavy JS Scripts.

Define "problems" please.

Generally I have JS disabled completely and enable it on specific sites only (and temporarily, in a dedicated window, without running any other apps while doing that, hopefully to avoid potential Spectre attacks).

So in such a scenario - is there any benefit in hardening those prefs?

[Atavic]

Benefits are that some potential exploits are blocked:
