Finalizing that change now, but...

I believe the myspell-cs versus hunspell-cs issue specifically, although 
triggered by parl-desktop-world, is caused by firefox-* (and 
task-czech-desktop not used by debian-parl) recommending only myspell-*, 
whereas libreoffice-*, thunderbird-* and lightning-* favor hunspell-* 
over mypsell-*.  I believe the latter - recommending either, and 
(generally¹) favoring hunspell over myspell - is correct.

debian-parl avoids hunspell-cs to be able to install locale packages not 
only for libreoffice/thundebird/lightning but also for firefox, but it 
is no surprise to me that APT may have trouble resolving a solution 
involving a selection discouraged by the majority of a package set.


> Please also check the other *spell dependencies.

firefox-esr-l10n-* for these locales recommend only myspell-* where 
hunspell-* also exist, so should _additionally_ recommend hunspell-*:

 * da (myspell favored¹)
 * bg
 * cs
 * de (hunspell-de-de | hunspell-dictionary-de | myspell-dictionary-de)²
 * el
 * es-ar
 * es-es
 * fr (hunspell-fr | myspell-fr | myspell-fr-gut)
 * he
 * hu
 * nb-no (no)
 * nl
 * nn-no (no)
 * pl
 * pt-br
 * pt-pt
 * ru
 * sk
 * uk

firefox-esr-l10n-* for these locales recommend dictionary only via 
transitional package, so should replace with _only_ hunspell-*:

 * ca (both real 0.20111230b-9 and transitional 3.0.1+repack1-3 exist)
 * en-gb
 * en-za (also wrongly transitions to en-gb)
 * it
 * lt
 * sl
 * sv-se (also should include and maybe¹ favor hunspell-sv)

firefox-esr-l10n-* for these locales recommend no dictionary and both 
hunspell and myspell exist, so should recommend _both_:

 * es-cl (es)
 * es-mx (es)
 * gd
 * hr

firefox-esr-l10n-* for these locales recommend no dictionary and only 
hunspell exist, so should recommend _only_ hunspell-*:

 * af
 * an
 * ar
 * be
 * bn-bd (bn)
 * bn-in (bn)
 * br
 * bs
 * eu
 * gl (hunspell-gl | hunspell-gl-es)³
 * gn
 * gu-in (gu)
 * hi-in (hi)
 * is
 * kk
 * km (kmr)
 * ko
 * ml
 * ro
 * si
 * sr
 * te
 * th
 * uz
 * vi

firefox-esr-l10n-* for these locales recommend no dictionary and only 
myspell exist, so should recommend _only_ myspell-*:

 * fa
 * ga-ie (ga)
 * hy-am (hy)


¹ myspell-da is arguably technically superior to hunspell-da: The former 
is built from a much larger wordlist - the latter is promoted by Mozilla 
and LibreOffice due to a more liberal license.  Similar licensing issue 
for -se dictionaries - uncertain which of those is technical superior.

² german myspell packages do not provide virtual hunspell-dictionary-de

³ uncertain which should be favored


Yes, above issues should ideally be reported separately - I thought I 
did so about a year ago, but apparently got axhausted before finishing 
reports for icedove and iceowl.  Help passing on the info to firefox 
much appreciated.
