Jahia multivalue size limitation

Since a long time jahia_multivalue content is stored in a simpleText field and it has always been a nightmare, because it's impossible to store some content that our cleints would like to store in it. Would that be imrpovable in Andromeda (storing a string for instance, instead of a small text).

The recuuring will of customers is to store, for instance, a list of countries, or cities.... but it's just impossible.
