The value which seems most useful for javascript.

If there can be various competing choices, then indeed we have a problem.
The intention of electric-layout-mode is that it should more or less
(tho in a naive way) insert the newlines for you if you just
naively/sequentially type in the code.
There might indeed be various options as to "when" to insert the
newlines as well as "where".

I don't understand the question: if there are cases where
electric-layout-mode would insert a newline but the user doesn't want
it, indeed the user will be annoyed. I think in general there's no way
to be sure this never happens, other than turning off
electric-layout-mode. Same happens for the suggested
electric-pair-newline-between-pairs-rule.

{ not followed by a newline are rare in C, but they do happen, indeed.
E.g. for "enum"s or for immediate values of structs/arrays. So, indeed,
for those cases electric-layout-mode will be annoying.
For that reason electric-layout-mode is off by default, and I haven't
heard anyone argue to enable it by default.
>From this POV, maybe electric-pair-newline-between-pairs-rule should be
made into a separate minor mode, indeed. It will reduce your use of RET
much less than electric-layout-mode but it's less likely to be annoying.
Less gain and less pain.
