Yet another topic about static IP-addresses

This has been requested many times before, but since topics are closed very fast I had to open yet another topic about this issue.

For reference:

Internal systems like databases and API’s commonly use an IP-whitelist for security.
Other services often provide a list of static IP-addresses to whitelist, for example Google for connecting Apps Script to a JDBC database.
Exposing these systems to the whole world is a non-starter in many cases, therefore using the delightful Activepieces Cloud is not an option.

Based on this comment by @abuaboud in an earlier topic it seems like there’s now maybe potentially a list of static IP-addresses, with possibly a better setup coming in the future?
What’s the current status on this? Is it safe/reliable to use that list, and is there any update on this potential better setup?
