There won't be a single orchestration winner, orchestration will just become ubiquitous in LoB systems. Slack and Github will probably be the biggest targets but it's pretty simple to create a chat bridge that supports adapters to support discord/telegram/etc and you can already do webhook orchestration easily enough.

This is what we are looking at at one of my clients. A2A clients (Slack, Google Meet, considering email) to A2A Orchestrator server (in-house, might be open-sourced) with specialized subagents for e.g. GitHub issue creation following a specific teams patterns and conventions, hooked up to company-wide MCP gateway with federated OIDC trust for passthrough auth (https://www.gatana.ai)

Works pretty well so far. Biggest issue i foresee for success is user UX for average employee, and actually useful use-cases.
