I do not see any functionality problem from it, neither now and neither in the
future.

Both variants of this code:

#include <string>
template <typename T>
void f () {}
//int main () { f<std::string> (); }
int main () { f<std::basic_string<char> > (); }

produce the same DWARF output:
    <2afa>   DW_AT_name        : f<std::basic_string<char> >

So one cannot say that one or the other matches the source code more.

One can only argue whether DWARF DW_AT_name should be compressed or not.
