Novel form factors are often how laptop manufacturers distinguish themselves from their competitors. There is enough space within a desktop PC case to formalize a standard. As laptops get thinner and thinner, however, many engineering/layout tweaks are used to fit stuff within a thin chasis. Standardizing across different device models would be asking OEMs to stop putting efforts into competing with each other. And I say this as someone who has just had a catastrophic motherboard failure on their 8-months-old laptop and had to do a replacement that would've cost me a new laptop if outside warranty.
