Because OGC already has a suite of standards developed that are highly adopted in software applications, if we make PipelineML compatible with existing OGC standards, we can immediately be compatible with these software applications (ESRI, AutoCAD, Bentley, Integraph, etc.). This includes GML, WFS, WFST, WMS, etc. By adopting and extending these existing standards, we get an enormous amount of capabilities right out of the box.
