It *can* give an option to a user of the tool to decide if it should go 
ahead ignoring the extensions it did not understand even if they are 
optional extensions or minimally issue a warning message (as a 
configurable option say). Blindly ignoring and staying silent on the 
user is the worst thing a tool can do to a user. I may want to build a 
client that understands certain optional extensions I need to use. If 
the tool does not handle some of the extensions, I as a programmer may 
like to have an option to override and plug in my code as needed or at 
least be notified.

That way I can decide to buy tool-A that does not understand all the 
extensions vs Tool-B that does. May be some tool builders :-D would not 
like that.

Just putting forth a pragmatic perspective for discussion. Grab some 
cool-aid will you!!!

Common sense tells me not to blow my top off silly also :)
