Jira activites vs. WebAPI activities, RestSharp mismatch

Continuing the discussion from Method not found: 'Void RestSharp.Parameter…ctor(System.String, System.Object, RestSharp.ParameterType)':

Staying on WebAPI 1.9.2 is not a suitable solution in our case, as it prevent us from using essential functionality in the later versions (eg. reponse content output). Upgrading WebAPI breaks every one of our Jira scopes on version 2.4.1 of the Jira activities package, rendering our automated ticketing solution useless.

Will the Jira package ever be updated to fix this really annoying issue? The Jira system integration activities package is also pretty useless and hasn’t been updated in over 12 months.
