Adjustment/retirement of capitalized Capital Assets

Summary:

Implications of adjusting(amount) or retiring capital assets in FA module rather than in Project

Content (required):

I would like to understand the implications of adjusting or retiring the project sourced capital assets directly in Fixed Assets module after they have been capitalized. Is there any major impact (except that the information will not be sent back to Projects module)? Client plans to extensively use the adjusting amount functionality in FA, as well as possibly using partial retirements of asset in order to indicate a loss of value (instead of impairment/revaluation). Accounting wise everything seems fine, I was wondering if I am not missing any other major downsides to this.
