(snip) If it is the latter then why aren't there any gods in the FR pantheon with both the Skill and Strength domain?
Maybe because it didn't occur to the designers to do? I am sure it's not an active conspiracy to ensure that no FR deity doesn't have that particular combination but I am also sure that there are many other combinations that aren't represented yet.
It's easy enough to house-rule. Gond (assuming he is alive in your FR) or possibly Oghma would be suitable; perhaps a couple of the dwarven deities deserve a guernsey too.
One of the things I have liked about the post-1E incarnations of D&D that there are attempts made to match the themes to the mechanics. I don't always agree with the choices but, IMO, it's superior to the farcical situation (again IMO) that occurred in 1E's ToEE where all the clerics of different elements had the same spells.
