As I understand there are no no plans to add random write access to .
tab file, isn't it?

Exist other reason except perfomance to add this future.
When you update file by making a copy you pack new file.
So the ID's of same shapes in new file may change.
It's happens when I need to delete some shape in a middle. All shapes
with a biggest ID's will change it's values. :(

I see that idea that tab could be only read or only write cross over 
all source code of mitab :) What the reason of such design?
Suppose it's really hard to imlement random write access to .tab file,
due to complex .tab structure. Is it hard to implement append to tab?

How do you think, how many time need to add random write access to tab 
file?
What main changes that I need to do in mitab?

Thanks.

P.S.
I was surprised by clean design of mitab library.
Not so  frequent thing for the open source ;)
