I guess it depends on what you mean. If it means "currently placed doors won't work, you have to (and can) remove them and place them back to fix it", I guess it is ok. If it means "forget about doors, they will not be part of that game", I guess it is less ok.
At worst, couldn't you do a smart but not intuitive enum that would make both powered blocks work and doors work ? Like, if your door is currently 01xxxxxxx, then do
10=passively powered
00=actively powered (not intuitive)
11=not powered
01=not powered either
This way, the door isn't powered and 01xxxxxx is still available for it ;)
And no one cares about that door not being powerable, I don't think doors are powerable in Minecraft. I think the best you can do is open them if the block next to them is powered.

Now that I think of it, even a more intuitive enum like
11=actively powered
10=passively powered
01=not powered
00=not powered either
could work...

I own: 83+ ; 84+SE ; 76.fr ; CX CAS ; Prizm ; 84+CSE
Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

It's not that big of a problem ;)
Currently, BLOCK_WDATA is defined as uint16_t, the lowest 8 bits are the BLOCK (the ID),
the higher 8 bits could be used for anything.
Somewhere in crafti, there's the enum BLOCK_SIDE, which is used as the highest 8 bits of the door's BLOCK_WDATA.
To indicate whether it's the top or bottom half of a door, bit 7 is used.
For redstone power state, I'd use the top 2 bits (7 and 6) and I'd have to move the door part bit out of the way.
Then each door part would have it's part bit set to 0, which is bottom..

Edit: So that old doors won't confuse redstone circuits:
enum  REDSTONE_STATE {
NOT_POWERED=0b00,
PASSIVELY_POWERED=0b01,
NOT_POWERED_2=0b10,
ACTIVELY_POWERED=0b11,
}; or even better, a bitfield.

Doors are openable in Minecraft. This allows automagically opening them. ;)

I did a quick test:
This monstrosity can only be opened with the real bottom part..

Why do you need bits for opened or closed doors? Can't you just make a block which is an opened door and an other one which is a closed one ?

Does it matter where the bit is? In the BLOCK_DATA or BLOCK (number)?

You could use the free 8 bits for power level.

Which 8 free bits?

Edit: First test of some basic redstone

can you imagine, redstone computers on your Nspire?

Better, a redstone calculator on your calculator O.O.

Yo dawg, so I heard u like calculators so I build a calculator in yo' calculator so you can calculate while you calculate.

They're not free for doors:
