New Service Pack for OE 11.6 (eg. 11.6.4 to fix bugs)

Does anyone have any guesses about the likelihood of a service pack for OE 11.6?  I suppose it would be 11.6.4.

OE 11.7 is brand new as-of now (mid 2017) and we are unlikely to move to that version for years.  In fact, we are still on 11.3 in our production environment and are tentatively planning to upgrade to 11.6 this fall.  However one of the things that scares me about 11.6 is the poor quality of the latest service pack (OE 11.6.3), and the fact that Progress doesn't seem to be inclined to put out any more service packs for 11.6.  At least that is my understanding as of now.

Here are just a couple of examples of serious problems with 11.6.3 :

• Regression that crashes the database during backups for clients who use secondary buffers (see http://knowledgebase.progress.com/articles/Article/database-B2-crashes-with-1040-000078422 )
• Application crashing when using static datasets as "BIND" parameters (see http://knowledgebase.progress.com/articles/Article/passing-datasets-as-output-bind-on-windows-crash )

No doubt there are a number of minor issues in 11.6.3 that would NOT require a full service pack.  But I think that the inability to perform database backup would be a significant enough issue to warrant a new service pack.  See this thread for more details about the database crashing during backups: https://community.progress.com/community_groups/openedge_rdbms/f/18/t/30303 

Customer-specific hotfixes are OK but generally-available service packs are far better and are less intimidating than running a custom hotfix.

So my question is whether anyone else thinks its premature to stop producing service packs for OE 11.6?  To me it seems like Progress could provide better support to their customers by providing new critical service pack(s) that are needed for 11.6.  When see the following solution statements in the KB that already say "Upgrade to OpenEdge 11.7.0", this comes as a shock.  I imagine that it is unusual for Progress customers to be upgrading to OE 11.7 already, and that statement seems a bit out of touch.  Perhaps it is too costly to support the versions of Progress which are actually used by their customers.

Thoughts?  Is there a way for customers to vote on additional investment to fix the bugs in OE 11.6?
