It is not (only) *.la which sucks but the whole 'libtool' suite:

* when having a package which provides multiple libraries which are
  linked together, you could create an efficient

  libfoo0 -> libfoo1 -> libfoo2 -> APP

  dependency chain. With libtool you will always end with

                           libfoo0 --,
              libfoo0 ---> libfoo1 ---> APP
              libfoo0 ---> libfoo2 --'
  libfoo0 --> libfoo1 --'

* libtool reorders linker options, so that

  | -Wl,--as-needed -lz -lfoo -lbar


  | -lz -lfoo -lbar -Wl,--as-needed

  rendering the '-Wl,--as-needed' effectless

* libtool is a bloaty shell script slowing down the build process

* integration into automake makes 'make -s' useless

* it creates alwyas RPATHs in multilib environments (except you apply
  unofficial patches)
