Can fully understand as a hobbyist you wanting to operate everything to that degree of self custody purity but really the cost benefit ratio is debatable. For most people coinos will be more cost effective. I have seen some fee/cost structures where the entire average float of sats I hold on LN would be guaranteed consumed with a few years. I support coinos as it is a unique wallet enabling anyone easy, low cost access to LN MoE. By pooling sats on coinos very good liquidity and cost benefit is achieved.
