You could, if you want.

Nothing is broken, so how should it be fixed?
By the way, there is a special mailing list for ublas, just in case you really want that something in ublas gets "fixed".

Ignore this strange "safe-STL" stuff? Arbitrarily declaring certain STL functions as "unsafe" because certain types of errors cannot be detected at runtime doesn't make much sense to me. What should be safe about detecting errors at runtime? Is it really safe, if your program crashes because you wrote "c.begin()+i-1" instead of "c.begin()+(i-1)"? But I admit that you can switch the checks of before you ship your product, and running your regression tests with safe-STL enabled may actually show you some "possible" issues of your code.
