Slow initialization, l10n and Staticize

With the Staticize plugin enabled, WordPress seems a lot faster than before to me. However it still takes about 300-400ms to load – this has to be the time the framework itself needs to start up.
After placing some debugging code I found out that the main “performance eater” is the l10n framework, which takes a lot of time to load the German language files (with English default language instead of German, the page takes about 100ms to render).
Can / will this be optimized some time?
One way to avoid this is to manually load the Staticize plugin before everything else (i.e. after the “function*.php” files are included), but that’s not the most elegant way…
