It should only be for multi-file templates, as TextMate will do the  
check for single-file templates, and “bump” the untitled counter until  
there is a free spot. It can’t do that for multi-file templates  
because it only knows the name of one of the files generated (so that  
is the one it ensures does not already exist).

As for ‘fairly easy’ — with the default set of templates, only the  
Objective-C singleton generates multiple file. You can use this  
repeatedly w/o problems. What you have to do is use it, go into the  
temp. folder and delete the *.mm file w/o deleting the *.h file *then*  
a problem arise. But while easy, why would you do that? Why would you  
use the template without a project in the first place?

If you use the template with a project, you are asked for a name in  
advance, so the problem should not exist here, and IMO this template  
mainly makes sense to use for projects.

Sure it is: It doesn’t crash, it doesn’t lead to problems for 99.999%  
of users, the problems it can cause (no templates generated) are non- 
serious and easy to workaround (cleanup your temp. folder), at least  
when you know the issue, the intended use of the template should  
actually never lead to this problem, and finally, the “fix” is non- 
trivial, because this is more of a design flaw than a bug, it requires  
a rethought design which would likely break with the current template  
system, hence why this is scheduled for 2.0, where it is more ok to  
just drop support for the current templates.

Shell commands (and hence disk files) will not be involved in “New  
File [From Template]”, so there should be no such issue.
