[development] An alternative to common thinking in 5->6 migration

[Nancy Wichmann]

In moving modules from 5.x to 6.x it is commonly suggested to move our
“drupal_add_css” (and _js) into hook_init.  Ceratinly I did this in nearly
all my modules because it was the common suggestion. However, now that I’m
making a big change in one and having problems with the CSS, it dawned on me
that this suggestion adds the CSS files to *every* page, not just the ones
we were targeting. It finally dawned on me that I have hook_help that only
fires on the pages I need to CSS on, so I moved the “drupal_add_css” into
hook_help, which to me makes a lot more sense because now my CSS is only
applied to those pages for which it is intended.  What do others think of
this? Are there pitfalls I may not have covered?
