The thread that you replied to has nothing to do with application delimiters.  :)

Anyway, I don't think making this configurable is really a good idea.

It certainly does seem better to settle on a syntax and not do any magic 
character conversion internally for delimiters.  However, another part of me is 
still uncomfortable with the change in regards to the vast number of existing 
dialplans that will no longer work.  Furthermore, there is a vast amount of 
example dialplan around the internet that will no longer be correct.

It has always been a value of this project to put forth a best effort to 
maintain backwards compatibility.  In the cases where we decide not to maintain 
compatibility, it has been done over a two release cycle.  The first one has 
marked a given option or syntax as deprecated, with appropriate warning messages 
any time they are used.

Don't get me wrong, I am all for simplifying configuration.  I just want to be 
really sure that we don't fix one problem by creating a bigger one.  Also, I 
want to put forth a best effort to ensure that the upgrade path is as simple as 
possible.
