There is a lot of situation where application logs debug information. 
Adding details for openssl errors is very useful to find reason for 
failure based only of logs provided by user.

Recently an user report to me that it uses application with openssl 
version, a but based on openssl error information I found that its 
actual version is a+2 - function code does not exist in (a).  As result 
is was more easy to find what could be reason for errors.

 From my point of view current errstr utility is quite useful to find 
failed function. Error information could be enhanced. I cannot see 
reasons to strip it down.
