Like all things they have their place, but overuse can be a problem.

For instance they could solve the problem of getting an intial entry
point (code or data) into a kernel 'module' that has being linked
into a kernel with 'ld -r'.
(when modules are loaded it is possibly to do a symbol lookup...)

There are probably other places where it is difficult to call an
explicit initialiser.

It is all rather similar to the proliferation of memory pools - for
things where 'malloc' would be fine.
