lastmod from a meta tag

[Brand3000]

Hello! Wouldn't it be great to have an ability to set the lastmod into some meta-tag, If I don't want just set yesterday date or any specific date, but I want to use dates from my database?
Something like:
<meta name="date.created" content="{{ $currentPage->created_at ?? "" }}">
<meta name="date.updated" content="{{ $currentPage->updated_at ?? "" }}">
or
<meta name="content_origin" content="{{ $currentPage->created_at ?? "" }}">
<meta name="content_updated" content="{{ $currentPage->updated_at ?? "" }}">
