Removing XMP before distilling

Removing XMP before distilling

Hello,

In order to reduce the file size of a 100MB PDF containing tons of 
Illustrator eps I thought about removing XMP data before distilling.
The ps is generated by Latex' dvips, and the following crude awk script 
is used to remove the XMP data of the AI eps
   BEGIN {printit=1};
   /BeginClientInjection: PageSetup End/ {printit=0};
   /BeginClientInjection: PageTrailer Start/ {printit=0};
   printit==1 {print};
   /EndClientInjection: PageSetup End/ {printit=1};
   /EndClientInjection: PageTrailer Start/ {printit=1};

As an example the original ps is on
   <http://www.hft.ei.tum.de/mz/overhead.ps>
the resulting Distiller 8.1 generated pdf with and without the XMP data 
are on
   <http://www.hft.ei.tum.de/mz/overhead_with_xmp.pdf>
   <http://www.hft.ei.tum.de/mz/overhead_no_xmp.pdf>

Acrobat Pro 8 reports for the two versions

category	with_xmp	no_xmp
---------------------------------------

structure	17		0
overhead	57389		4805
ext graph mem	121		121
total		61785		9162

Do I have to expect unwanted side effects?

Best,
