Could you build this?
No Implementing an LSP 3.17-compliant language server in Go involves deep compiler engineering, parsing/AST generation, incremental semantic analysis, symbol indexing, and strict JSON-RPC protocol adherence.
What it would actually take: A developer needs Go, tree-sitter or custom lexer/parsers, and a structured JSON-RPC handling framework. The difficult aspects are incremental text document synchronization, semantic tokenization, type-checking, reference resolution, and managing low-latency symbol caches across massive codebases without blocking the main event loop.

Competitors mentioned: glsp - Go Language Server Protocol library
Concerns raised: Handler panics crash the server and don't keep connection alive, Godoc comment format requirement feels verbose for simple items
Feature requests: Debug UI to track LSP messages, Error recovery when handlers panic
