Trimming the front is entirely normal. If the manufacturer made the front derailure wide enough to use all of the rear cogs without trimming then the front wouldnt work, it would be to wide to shift the chain. Besides you are not supposed to use all of the cogs in the rear from the same ring up front this is known a s cross chaining and is hard on the bikes components. do a search on cross chainingand read.
