100% against enabling it by default. 

- still a BC break since some apps in the wild assume serialize($foo) is ascii text (whether
that's good or bad).
- the default serialize() is readable, easy to debug, doesn't assume you can read binary. PHP
is also about simplicity not performance.
- igbinary_serialize_double() is not cross-platform so serializing/unserializing a 'float'
won't always work
http://www.dmh2000.com/cpp/dswap.shtml (2. use
a 'union' type to overlay a byte array on top of the data)

My preference would be to have:

serialize_text()    -- ascii text only (standard/var.c) but remove 'NULL' byte (working on
a patch for this)
serialize_binary()  -- igbinary bundled into core...

serialize()         -- based on php.ini setting, serialize_text by default
