Well, next years or so, that's different. There is plenty of time

No. But if you want to make sure packages you built successfully
against glibc-2.6.90-* or later don't die at runtime for these errors,
it is pretty easy to just check all calls to __open{,at}{,64}_2
functions (i.e. calls which don't pass mode argument to open*
and it is not clear whether O_CREAT is or is not used at compile time),
they will be pretty rare and in each case you can study the code to
determine if the passed flags can contain O_CREAT or not. If they can,
you must supply the mode argument, if it can't, you are ok.
