Hmm, I see clang produces

COMDAT group section [    3] `.group' [_Z5IndexIiEvi] contains 2 sections:
   [Index]    Name
   [    4]   .text._Z5IndexIiEvi
   [    5]   .rela.text._Z5IndexIiEvi

COMDAT group section [    6] `.group' [_ZZ5IndexIiEviE3VAR] contains 1
sections:
   [Index]    Name
   [    7]   NEW_SECTION

COMDAT group section [    8] `.group' [_ZGVZ5IndexIiEviE3VAR] contains 1
sections:
   [Index]    Name
   [    9]   .bss._ZGVZ5IndexIiEviE3VAR

and if I add a Index<float> specialization it ends up emitting two
distinct sections with the same name NEW_SECTION and
