The original basic design model for the Skyfire SVM-0 mill I bought came out with an ER32 spindle end and a 1 HP BLDC motor etc etc, but I pushed for the ISO 20 spindle option with an additional option to have a self contained water cooled High Speed spindle change over capability for carving etc ......and paid accordingly...….. but it did give me interchangeable tooling and a power draw bar which is the main reason I went ahead and bought it.
If you were designing the ideal mill...….. size whatever...... the main aspect would be it's milling capacity as opposed to the economy, but if it was for a sale item then you'd have to cut many corners just to compete in a very tight market......the market is saturated with mill options from the very cheap and retrofittable to the exotic high end commercial stuff., it just depends on what you intend to use it for...…..hobby work is a totally different ball game.
BTW, the specs for the spindle you linked showed a usable rev range from 2,000 to 6,000 not 0 to 6,000, that is a big limiter.
