Currently the site.userblock() function does not have a parameter for allowusertalk; consequently, all blocks made using pywikibot result in blocking the user from editing their talk page as well (because the default value for this option is true). The API has supported the allowusertalk option for many years; it is time for pywikibot to also support it.
