Anyone see this? Looks like the bulletin came out last October. I don't know how to link the bulletin here, so I just copy and pasted it. The bulletin number is TSB150147. Got it off of Quickserve. Curious what people think. Good idea? Or hogwash?

Description of Change
This document announces the release of a maintenance-free crankcase breather insert for external crankcase breather systems and advises the field of a part number change for the existing crankcase breather filter element.
The new maintenance-free crankcase breather insert is a direct fit replacement for the existing crankcase breather filter element but does not require a filtration media to function.
Reason for Change
The maintenance-free crankcase breather insert has been released to eliminate the need for scheduled replacement of the existing crankcase breather filter element and reduce associated maintenance costs.
Customer Communication
The crankcase breather filter element that requires replacement at regular maintenance intervals is not being obsoleted. This is being done in support of customers that want to continue to use the previous design and do not want to convert to the new maintenance free design.
Service Parts Availability
Service parts are available. See Table 1 below for part numbers.
