Auto Associate Contacts when an additional domain is added on the company level

What?
HubSpot should auto-associate contacts to a company record if the contact’s email domain is a part of the company’s ‘additional domains’.

Why?

In some industries, it is very common for Companies to get acquired, when this happens, as a HubSpot admin it is easier to update the HQ company with an additional domain (of the acquired company) instead of merging the accounts because we don’t want to update any info on the primary/main account.
When this additional domain gets added, the contacts don’t automatically associate themselves with the company record.
It’d be nice if that could happen automatically so in that case the admin can just delete the ‘acquired company’ record instead of manually reassociating and then deleting

It’s amazing that this hasn’t gained more traction in a year; this seems like a simple IT fix.

I also wanted to paste this URL for a similar idea in the hopes that one or both will receive enough attention that HS will implement these suggestions. https://community.hubspot.com/t5/HubSpot-Ideas/search-on-additional-Domains/idi-p/522433#reply
