The problem is still happening
The table in my previous answer includes several posts scoring below -8 based on the first two daily voting summaries. Only two were created before this question was posted. The other eight were created after 2019.
I'm not claiming that they deserve special attention; the claim is that considering the Meta Stack Exchange's purpose and the community behavior, they don't deserve less attention.
Supporting arguments
Community behavior
The Meta Stack Exchange community uses upvotes / downvotes early and often. By this, I mean that many users vote up or down on new posts on the same day they were posted, sometimes even in the first hours. Over the years, there have been calls to change voting behavior in Meta Stack Exchange. Some complain about being unfairly downvoted; others appeal to motivations, rationalizations, etc.
As of October 2023, there have been heavily downvoted posts that aren't crap. Most crap posts are spam or abusive, which are been deleted.
Meta SE has changed
The idea of hiding posts with a low score comes from main sites. The threshold was changed to adapt it to per-child metas, but Meta SE is different.
Meta SE has an active core community
The workings of Meta Stack Exchange have changed. Nowadays, Meta Stack Exchange has Community Moderators, and the posts requiring staff intervention have changed.
Moderators could add the tag status-review to the posts that the moderators consider that the Community Managers should pay review to be escalated internally.
About the workarounds
Using featured
This might be good enough for staff posts. This could not be used for non-staff as the post will be shown on the Community Bulletin of all Stack Exchange sites, and not all the user-created communities might require such exposure.
Using Questions (page), Filters
Considering the site's purpose and community behavior, this solution is satisfactory for Meta Stack Exchange power users but not for a permanent Homepage state.

Upcoming initiatives on Stack Overflow and across the Stack Exchange network (March 2024)
If I understood correctly, in 2024, Stack Exchange, Inc., regarding the public Q&A platform, announced the initiatives that they would be working on. This includes "Discussions," a feature launched as an experiment in 2023 as part of Overflow AI. It continued with the same status in early 2024.
One of the recent changes to "Discussions" is the removal of the downvotes on "Discussions" posts as a "sub-experiment" (an experiment inside of a more significant experiment).
I found Discussions at too early stage to consider making a feature-request pointed to solve the problem discussed here.
