Removing discovery service from GEMOC Studio ?

In the latest version of Eclipse (Modeling 2020-03) the amalgam project that offers the base classes of the discovery service isn't included anymore

the last version of amalgam is 3 years old (cf. https://projects.eclipse.org/projects/modeling.amalgam)

This raises the question of "should we try to maintain this in the Studio (and relying on unmaintained component) or simply remove it ?

Apparently, other package replace this service by a marketplace where we could try to expose tool by asking contributers to use some "GEMOC" tag.

Note: I need a rapid agreement about removing this because I'm upgrading the studio to Eclipse 2020-03
