I don't think so.  (See below.)

I believe there is.

To me:

  - The tlscertfile is the local machine's certificate.  It should 
/only/ be accessed by processes on the local system.  --  HIGH security.

  - The tlscafile is a copy of public certificate(s) from certificate 
authorities.  It (they) can be accessed by anyone.  --  low security.

My personal opinion is that the HIGH security and low security contents 
should *NOT* be /mixed/ in the same file.

Aside:  There may be some quibble room over public vs private part of 
the certificate and wherever the associated key is stored.  (I don't 
remember off hand.)  The key /definitely/ should *NOT* be co-mingled 
with anything else of lesser sensitivity.

I think it would be detrimental to security to share a common 
certificate for multiple services.  This was highlighted by the recent 
ALPACA Attack (alpaca-attack.com).
