Does this change cause the rule to produce more or fewer warnings?

fewer

How will the change be implemented? (New option, new default behavior, etc.)?

new option

Please provide some example code that this change will affect:

/* eslint  no-extra-parens: "error" */
/* eslint  no-sequences: "error" */

(a, b); // 'no-extra-parens' warning

if ((a, b)); // 'no-extra-parens' warning

What does the rule currently do for this code?

Fixes it to:

/* eslint  no-extra-parens: "error" */
/* eslint  no-sequences: "error" */

a, b; // 'no-sequences' warning

if (a, b); // 'no-sequences' warning

while(a, b); // 'no-sequences' warning

What will the rule do after it's changed?

/* eslint  no-extra-parens: ["error", "all", { "sequenceExpressions": false }] */
/* eslint  no-sequences: "error" */

(a, b); // no warnings

if ((a, b)); // no warnings

while((a, b)); // no warnings

Are you willing to submit a pull request to implement this change?

Yes

Unfortunately, it looks like there wasn't enough interest from the team
or community to implement this change. While we wish we'd be able to
accommodate everyone's requests, we do need to prioritize. We've found
that issues failing to reach accepted status after 21 days tend to
never be accepted, and as such, we close those issues.
This doesn't mean the idea isn't interesting or useful, just that it's
not something the team can commit to.

Thanks for contributing to ESLint and we appreciate your understanding.

@eslint/eslint-team This just needs a champion and we could accept this!

[kaicataldo]

I'll champion this.

[mdjermanovic]

I'm working on this :)

What should be the name of the new option? The last was enforceForArrowConditionals

Maybe enforceForSequenceExpressions instead of just sequenceExpressions?

[platinumazure]

I like enforceForSequenceExpressions personally. I generally don't like option names without a verb indicating what will happen if you turn it on. (Just my two cents; other team members may have their own opinion.)
