_clear property - is it safe to use in production?

[krzysztof-studnicki-booksy]

Hi,
we need to use the _clear property that is described here https://github.com/google/data-layer-helper?tab=readme-ov-file#preventing-default-recursive-merge, but we're not sure if it's something that can be used in production.

It solves a problem that we have, but there's no mention about it in GTM docs, so I figured we could ask you there.

We are using _clear in production for a year or so and it has been working great. Obvious danger would be an undocumented change that breaks this functionality, but so far so good.

[If that's too scary, the more hacky way that also works is that you can just push two events. First, what I'd call a 'clear' utility event (eg push an 'empty' event with only the variable(s) in question, where all of them are set to a value of undefined - the event name can be anything you pick). Then, simply push your 'real' event with all the good data.]
