Did Madagascar reshape landing-craft development?

What part did the Madagascar landings play in the development of landing craft?

Very little; strong naval fire support overwhelmed the defences, so the operation revealed few new landing-craft requirements.

Madagascar appears less influential than exercises and operations that exposed genuine gaps in craft or doctrine. The Royal Navy already practised concentrating ships, including major units, to support landings. At Madagascar, available naval firepower was sufficient to overwhelm the opposition.
