Wow OP there, I didn't think anyone would pass by my random blog and post the link here .... I'm surprised at the number of comments for a post that was originally there just to feed my blog with a first page and provide a bit of content. Especially for an article that I feel is barely finished and needs a lot of updating.

No this is a common rule in industry in particular.

The more components you add a component into to a defined system (excepted for redundancy purpose), the higher the probability of failure.

This is exactly why Toyota provides tier A car in term of reliabily and majority of European / US car full of failures by adding a lot of useless gadget.
