Currently we have many different formats for phylogenies (e.g., nexus, newick, extend newick, phylip, xml) and there is no doubt that putting in place a Phylogenetic Standard would be a good thing but just because a group of researchers get together and decide that a Phylogenetic Standard would be good doesn't make it happen. Unless the phylogenetic community is behind the decisions being made which is unlikely to happen any time soon as phylogeneticist already have a poor record of submitting their phylogenies to databases like TreeBase.
These are obviously points that you are aware of as you mention them in your statement. I only remark that unless publishers enforce a particular format and submission of the phylogenetic data into repositories (like GenBank/EMBL), then however noble the idea of a Phylogenetic Standard is, it is unlikely to be put into practice by phylogeneticists.
