Myths? No. Those are Truths.
Short scales (anything less than 35" scales) are amateur basses and only for students with small hands. String tension is higher with longer scale lengths, and good string tension is necessary for any professional.
Neck-thru is simply a better-construction method and a more sound design. Bolt-on necks should be reserved for short-scales (aka student instruments). There's no use in making amateur basses with better quality. When the bassist is good enough, he should upgrade to a pro instrument.
5-strings are the old 4-strings, and 6-string are the new 5-strings. What that means is that 4-strings are obsolete and 5-strings are the new standard for students and amateur-grade instruments. Pro bassists should not, under any circumstance play fewer than 6-string basses.
Active electronics are ALWAYS better than passive electronics. Firstly, active electronics can cop that "vintage, passive feel" that some of the older generations prefer (even though they are no longer acceptable in today's music). Active electronics are a must for pro instruments (again, passive should be left for the not-so-professionals) because all situations a pro bassist will encounter require on-the-fly EQ changes to suit the house mix and overall band sound.
This may seem a bit rash, but there is way too much diversity among bassists these days, and conflicting views lead to arguments that have no justification and are based on "preference." By mandating some of these changes, the system is better conformed, but leaves ample room for personality (wood types, paint jobs, scale lengths above 35", number of strings above 6, hardware type and color, onboard preamps, pickups...etc). However, it also sets clear lines for amateurs and pros so that the unworthy amateurs with little musical ability can stop saturating the market and let true artists fill the roles they deserve.
HAHAHAHAHAHAHAHAHAHAHA
