I saw some ideas at forum considering merging servers; as it's technically hard to merge servers phisycally, it would be fun at least to have shared global chat for servers; making chat 'bridge' shouldn't be too hard technically but would give more interaction between players

It's not more easy than merge servers

It's 100 times easier Cause for merging servers you have to operate with DBs and it could mess with players housing & etc; and for chat relay you don't need interact with DBs at all.

There are loads of cooked up bridges around; for example, recently I made bridge between IRC and Discord and there are a lot of open source solutions for this, like:
https://github.com/Headline/Discord-IRC-Relay or https://github.com/reactiflux/discord-irc

I believe creating bridge chat relay between game servers could be also pretty manageable, especially for such professional team like Virtys

For the moment we can't. We have no other answer.
If it changes in the future you will see it

(don't forget that each game is coded in a unique way... and "easy things" for a game isn't easy for another game).

Sure, every project is unique! I'll cross my fingers
