Maybe something more neutral just meaning a virtual element / no-element container would better express the intention? And regarding the syntax, maybe it would also feel less repetitive / boilerplaty than <svelte:slot slot="name" />... Maybe something like <svelte:fragment slot="name"> or <svelte:virtual slot="name">?

Also agree that <svelte:slot> is perhaps a little confusing since it replaces the slot attribute rather than the slot element, so <svelte:fragment> would make more sense

Fixes #1037 allow slotted components via making <Component> <Inner slot="foo" /> </Component> as a sugar syntax for <Component> <svelte:fragment slot="foo"> <Inner /> </svelte:fragment> </Component>
