I guess it is just a good practice in general.

Yeah, it's also one of my peves with scientific writing on the internet in general. Most authors just do not provide enough bread crumbs for the reader ( and people are lazy, if you don't lay it out for them, they probably won't go find it on their own ). The presence of easily accessible cited material would give people the opportunity to really take much more away from your article.

Talking about more things from a pure genetics standpoint is something that I haven't seen anyone on here do, I wrote some VERY general background pieces on DNA/replication/protein expression/ribosomes in the past. I suppose the way you go about it depends on the audience you are targeting (keep in mind that the audience here is largely non scientists, so boiling down the concepts to be as simple and digestible as possible really aides in people taking positive information away that they could apply to future readings).

Although it is very unlikely the time and effort is going to be spent into doing such research any time soon. You also have to take into account population control as well as a result of curing all illness. VERY tricky area of research.

Yep, yep, and definitely yep.
