I'm just saying that the quote is an excerpt of a book that describes 
how Firebird worked at that time (probably reverse-engineered using a 
lot of trial and error). It is not a prescription (requirements 
document) how Firebird is supposed to work. As such, it shouldn't be 
taken as the holy truth to which Firebird must conform.

I prefer backwards compatibility, but there are a lot of oddities in 
that described behaviour, some of which are not worth to preserve IMHO.
