This is worth swapping password managers over. I expected my search for integration to lead to a developer announcement about integration, not actual, ignorant responses from support about how it doesn't do what it does. Their database grows daily. The security challenge surely didn't pop up last time I got an email from HIBP about a breach, to a web site I had forgotten about. Nevermind the major ones. Billions of records, searched by hash (not just Collection #1, but half a decade of breaches). He's hoping to notify partners of customer data in the future, so we would know, immediately, without a search, if we'd been breached. LastPass doesn't do that, either.
Looks like the competitor that has it integrated offers a family plan for less than half the cost of one of my LastPass subscriptions. Don't leave it worth the effort to swap for a feature that should already exist or be in the works.
