I think in general it is a very wise idea to first target 1 market segment and completely dominate that segment before we move to another segment. If that first segment is RWA because of narrative and momentum, i'd say we go for that.
This has large advantages in terms of communication, marketing & sales as well. Easier to distinguish our selves ('branding') from others. Targeting everything with a small team and budget usually means nothing is really effective.
