I don't think they will ever add such features. It would open MT5 to the outside world and for sure it's a security issue.

IMHO surely not more than manually allowing usage of DLL in EA / Service.
Maybe a list of allowed listening ports would be a good security precaution ?
Hopefully these functions could be added in the near future MQL releases.
Thank you.
