Ubuntu and language packs

[Surfaz Gemon Meme]

Hi! I have some doubts

* Why Ubuntu install English support by default, although I chose
Spanish support?

I don't want waste 130~ mb space of my hard disk.

It strikes me that during the installation of Ubuntu is uninstalled
many languages (first, why install many languages? I only want one!!),
but no English.

In a few words, I think these packages are not required in any
non-English installation:

" aspell-en gimp-help-en hunspell-en-us language-pack-en
language-pack-en-base language-pack-gnome-en
language-pack-gnome-en-base language-support-en
language-support-translations-en language-support-writing-en
myspell-en-au myspell-en-gb myspell-en-za openoffice.org-help-en-gb
openoffice.org-help-en-us openoffice.org-hyphenation-en-us
openoffice.org-l10n-en-gb openoffice.org-l10n-en-za
openoffice.org-thesaurus-en-au openoffice.org-thesaurus-en-us
thunderbird-locale-en-gb wamerican wbritish "

In addition of English support, there are other things that I want to comment

* Why Ubuntu install thunderbird support by default (installing
Spanish support) althougt I no use thunderbird... and thunderbird is
no installed by default... O_o

* If it were the case I use thunderbird, why install Ubuntu packages
package thunderbird-locale-es-ar and thunderbird-locale-es-es?

I say that Depends field of "language-support-translations-es"
meta-package should be:

"Depends: openoffice.org-help-es, openoffice.org-l10n-es,
thunderbird-locale-es-ar | thunderbird-locale-es-es, gimp-help-es"

instead of:

"Depends: openoffice.org-help-es, openoffice.org-l10n-es,
thunderbird-locale-es-ar, thunderbird-locale-es-es, gimp-help-es"

In this way at least I could uninstall "thunderbird-locale-es-ar"
without uninstall "language-support-translations-es" package.
