Clean up amino acid metabolic process grouping terms

[edwong57]

Elisabeth Coudert from RHEA suggested that these are not useful grouping terms and should be cleaned up/obsoleted

GO:0009069 serine family amino acid metabolic process
GO:0009078 pyruvate family amino acid metabolic process
GO:0009066 aspartate family amino acid metabolic process
GO:0009064 glutamine family amino acid metabolic process
GO:0000820 regulation of glutamine family amino acid metabolic process
GO:1902221 erythrose 4-phosphate/phosphoenolpyruvate family amino acid metabolic process
& the corresponding biosynthetic/catabolic processes

not useful grouping terms

Hmmm. Quick searches suggest that diverse workers do find this grouping / classification strategy useful, e.g., "The aspartate pathway is responsible for the biosynthesis of lysine, threonine, isoleucine, and methionine in most plants and microorganisms."; CHEBI:26463 - pyruvate family amino acid. And these usages correspond to metabolic functional similarities among the members of each family. What specifically is said to make them UNuseful?

@deustp01, good question. @pgaudet, can you clarify with more details? Did she have specific suggestions?
